METEORITES FROM AFRICA, ARGENTIA, RUSSIA, AND OTHER WORLDWIDE LOCATIONS. METEORITES MAY CONTAIN IRON AND NICKEL, OR MAY JUST BE MADE OF ROCK, BUT THEY ARE ALL FROM OUTER SPACE AND SOME ARE AS OLD AS THE UNIVERSE ITSELF. INDOCHINITE TEKTITES WERE FORMED 700,000-800,000 YEARS AGO IN THE AUSTRALASIAN STREWNFIELD. PART OF THAT STREWNFIELD WAS IN MAOMING, GUANGDONG PROVINCE, CHINA AREA WHERE THESE WERE COLLECTED.
